One question I have is this: how did you get 7 megs on your card.  The
Plus only goes up to 6 megs unless you have a piggy back board attached.
If you have one, perhaps the diagnostic software ignored the piggyback
when it tested the card.  I would suggest moving the file in smaller
chunks, since there really is no place for all the extra info to go
between changing partitions.  There shouldn't be that many times when it
would be impossible to split up a folder into smaller components.
